Frequently asked questions

What does URL encoding do?
It replaces characters that are not safe in a URL — like spaces, &, ? and non-English letters — with percent codes such as %20, so the URL stays valid.
Is my text uploaded?
No. Everything runs in your browser using the built-in encoder. Nothing is sent to a server.
